Specification of Letters Patent. I Patented i Application medapril '12,1912. Serial No. 690,829.

To all it mag concern:

. Be it known that we, CHARLES B. SISLER and J Ants DnAvaNPoR'r, bothcitizens 'of the United States, .and residents of. Timberville, inthe-county of Calhoun and State of Mississippi, have invented anew andIm I and arrangement of interlocking flanges, as

hereinafter particularly described.

Reference is tohe had to-v the accompanying drawings forming a' part ofthis specification, in which similar characters. of reference indicatecorresponding parts in all the-views.

Figure 1 a side elevation of portions of two pipe sections, providedwith our im proved joint; Fig. 2 is 'a vertical section; Fig. 3. is afragmentary view-showing'a portion of the blank from which the outersection of the joint is formed; and Fig. 4 is'a similar view of theblank from -which the inner section of the'joint isformed:

In carryingout the'invention, the outer pipe section 10 or' that sectionwhich receives an adjacent section within an end thereof, is formed withan elongated slit 11 and short parallel. slits 12 at the ends of theslit 11; thereby producing, a U- shaped 'cut in the blank, leaving aZongue' which is .bent inward and upwar parallel with the section-10forming an oblong return flange 13 which desirably 1s rectangular, thesaid flange being spaced from the body 10su'flicien tly to receive asimilar flange formed on thead acent sec- .tion. 15. The said section 15is adapted to enter. the-end of the section 10, and the blank from whichthe section 16 is produced is forined with an elongated'slit 17 andshort parallel slits 18 at the ends theretlanges hold the-sections in Jp g sagging or accidental separa fi th sec- I of, presenting a- U-shapedcut, as lin theother section, thereby producing a tongue 19. The tongue19 is bent outwardly and 'returned parallel'wit-h the section'lfi to forin" an elongated flange, as shown clearly in Fig.2, which is receivedbetween the flange 13 of the companionsection-and thehody 10 of saidsection. The tongues'f13, 19 are inclined to the length of the-pipe, andwhen the two sections are assembled, the flanges are parallel with eachother, the one bing bent downwardly and the'ot-h'er upwardly tointerlock. In connecting the sections, the

relatively to each otherto bring the flanges against each other, andjasthe flanges are inner section. The positive interloekingof the flangesmakes a firm inter-engagement between the sections, and it' "-1be'obvious that with our improved- .j Q V stove pipe is projected htions. One or both of thefs'e cent to .the flange portion" t shoulderedor offset, as at 22, so turned flange of the section so bent in linewith the remainder of the section.

'By striking up the tongues toformflanges,

the joint is produced at minimum'expense; Having thus describedour,,1'nvent1on,-' we claim as new and desire to secure by'LettersPatent:
